Uniview No Continuous Recording: Troubleshooting Guide

Is Your Uniview System Failing to Record Continuously?

For any security system, continuous recording is a critical feature. It ensures that you have a complete, uninterrupted timeline of events, which is essential for comprehensive surveillance. When your Uniview NVR or camera fails to record 24/7, it creates significant gaps in your security coverage, leaving your property vulnerable. This guide will walk you through the common causes of this issue and provide a clear, step-by-step process to resolve it, getting your system back to reliable, round-the-clock recording.

Common Causes for Continuous Recording Failures

Several factors can disrupt your Uniview system's ability to record continuously. Understanding these potential causes is the first step towards a solution.

Incorrect NVR or Camera Settings

The most frequent cause is a simple misconfiguration. Your system might be set to record only on motion detection or during specific, limited hours. This is often the default setting, and it needs to be manually changed to ensure continuous operation.

Hard Drive (HDD) Issues

The hard drive is the heart of your recording system. If it's failing, full, not properly initialised, or incompatible, your NVR won't be able to save footage correctly. Physical damage or bad sectors on the drive can also lead to intermittent or complete recording failure.

Power Supply and Connection Problems

An unstable or insufficient power supply can prevent the hard drive from functioning correctly, even if the rest of the NVR appears to be on. Likewise, a loose SATA or power cable connecting the hard drive to the NVR's main board can interrupt the data transfer required for recording.

Outdated Firmware

Firmware bugs can sometimes cause issues with core functionalities like recording. If your Uniview NVR or cameras are running on outdated firmware, it could be the source of the problem.

Step-by-Step Troubleshooting Guide

Follow these steps in order to diagnose and fix the problem.

1. Carefully Verify Your Recording Schedule

First, you must confirm that the system is actually configured for continuous recording.

1. Log into your NVR: Access your NVR's interface directly with a connected monitor or via a web browser on your computer.
2. Navigate to Settings: Find the 'Storage' or 'Record' section in the main menu.
3. Select 'Schedule': Within this section, you will find a scheduling interface, often a grid representing the days of the week and hours of the day.
4. Choose the Correct Camera: Select the camera that is not recording correctly from the dropdown list.
5. Set to 'Continuous': Ensure the recording type is set to 'Continuous' (or sometimes labelled 'Normal' or '24/7'). The entire grid for that camera should be coloured in (usually green), indicating continuous recording is active for all hours.
6. Apply and Save: Make sure to save your changes before exiting the menu.

2. Inspect the Hard Drive Status

If the settings are correct, the next step is to check the health and status of your hard drive.

1. Go to Storage Management: In the NVR's settings menu, find the 'HDD', 'Disk', or 'Storage' management area.
2. Check the Status: The system will display all installed hard drives. Look at the status column. It should read 'Normal' or 'Healthy'. If it says 'Error', 'Uninitialised', 'Not Formatted', or is blank, there is a problem.
3. Format if Necessary: If the drive is new or showing as 'Uninitialised', you will need to format it using the NVR's built-in tool. Warning: This will erase all data on the drive.
4. Check for Errors: Some systems have a S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) test feature. Run this test to check for underlying drive failures. If it fails, the drive needs to be replaced.

3. Examine Physical Connections and Power

A poor connection can easily mimic a failed drive.

1. Power Down: Completely power off and unplug the Uniview NVR.
2. Open the Case: Carefully remove the cover from the NVR unit.
3. Reseat Cables: Locate the hard drive inside. Disconnect and firmly reconnect both the SATA data cable and the power cable running from the NVR's main board to the drive.
4. Check Power Supply: Confirm you are using the specific power adapter that came with your Uniview NVR. Using a different adapter with lower amperage may not provide enough power to run both the NVR and the hard drive simultaneously.
5. Power Up: Close the case, plug the NVR back in, and turn it on. Check the HDD status again.

4. Update Your System's Firmware

If the issue persists, a firmware update can resolve underlying software bugs.

1. Find Your Model: Note the exact model number of your NVR.
2. Visit the Uniview Website: Go to the official Uniview support or download centre website.
3. Download Firmware: Find the latest firmware version for your specific model and download it to a USB flash drive.
4. Update the NVR: Insert the USB drive into the NVR, navigate to the maintenance or upgrade section in the settings, and follow the on-screen instructions to apply the update.

By systematically working through these steps, you can identify and resolve the vast majority of issues preventing your Uniview security system from recording continuously.
